Re: 401 - need opinions .
A 401 make good low end torque, so you can use a fairly large cam and not lose low RPM torque. Here is the combo I am running now. Stock rods, and crank. Forged stock replacement pistons( aprox 10:1 compression). Mild bowl ported heads. Stainless valves. Competition Cams 280 magnum cam. Performer intake. 750 vacuum secondary Holley. I still have to do the oiling modifications, and future plans call for roller rockers, and an adjustable valvetrain. This engine pulls hard from idle past 6000 RPM, and I can idle it down to 500 RPM without stalling. When it is running right I can stab the throttle in 4th gear low range from an idle, and not have a stumble. I have also found it has to much torque for a stock replacement 10.5 inch clutch. You are making a great choice, and you won't be dissapointed.
